OK, so I bought some Weyermann Floor-Malted Bohemian Pilsen Malt as the majority of a large (for me) grain bill. The malts are all crushed and mixed together.

So then I read this week that this malt is undermodified and a multiple decoction is required. (Not going to happeen.) Northern Brewer doesn't post malt spec sheets in their retail store.

Is this true? Am I going to have to dump this grain bill?

Even "undermodified" modern malt is plenty modified. You're fine.

I seem to remember this group having an extensive discussion on how the "undermodified" aspect of the malt is basically negligible, since it is "undermodified" for that specific malt, but is relatively speaking (to other malts) not undermodified. I dunno. Gary said it, so I basically only caught half of what was going on.

You should be fine. I did a write up on this malt a week ago for the Tuesday reddit thread. I've had nothing but excellent results from it, and I'd say my efficiency has gone up since making it a go-to base malt.

You can download all of their general malt specification guides... it's a bit old (2014 date) but I know of two Austin breweries that use this product SOLEY as their base malt for all of their beers. Both quote consistency in crush, yield and flavor.

Just a point or two lower in dry extract yield than their normal pils and a Kolbach Index of 38-44...

That about sums it up.

I'll just copy my post in here, compare the numbers, the differences in extract are minor:

You can see that the Floor Malted has a slightly lower extract potential than the two non-floor malted varieties, this is because the Hartong Index (Extract Modification) is slightly lower than the non-floor malted. However the Kolbach Index (Protein Modification) is higher than the non-floor malted pilsner so it has more soluble proteins to help it survive a decoction mash without losing too much protein to maillard reactions. However all of these differences are minor, so all of these malts are perfectly suitable for infusion mashing.
